Venus​

​1. A day on Venus is longer than a year

It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That’s 243 Earth days to rotate once - the longest rotation of any planet in the Solar System - and only 224.7 Earth days to complete one orbit of the Sun.

2. Venus is hotter than Mercury despite being further away from the Sun

Its mean temperature is 462°C. This is because of the high concentration of carbon dioxide in Venus’ atmosphere which works to produce an intense greenhouse effect, trapping heat in the atmosphere like a blanket and causing the temperature of the planet to be much higher than its proximity to the Sun would suggest.
